My girlfriend's big butt is my ultimate fantasy

I've always had a thing for big butts, and my girlfriend's got one of the best. It's my ultimate fantasy to see her bent over, taking it deep in her tight little hole. I've been waiting for this moment for so long, and now that we're finally alone, I'm ready to make it happen. I can't help but stare at her round ass, imagining how it would feel to be inside her. She's got this seductive smile on her face, like she knows exactly what I'm thinking. We're both amateurs, but we're not shy about showing each other what we want. I start off slow, teasing her with my fingers before plunging inside. She moans in pleasure, pushing back against me as I go deeper. It's everything I've ever wanted, and I know this won't be the last time we'll do this.
